The price of the product before promotional sales was 500,000.
<h3>How to find out what the previous price was?</h3>
To find what the previous price of the product was, we must take into account that we know that 87% of the value is equal to 435,000. So to find out how much the 13% (discount) that the product had is equivalent to, we do the following operation:
435,000 × 100 ÷ 87 = 500,000
So we know that the 13% discount was 65,000

Answer:
4. y+3=-1/3(x-9) 6a. 15x-y=0 6b. $150
Step-by-step explanation:
4.
Point slope form formula: y-y1=m(x-x1)
Includes origin and point (9,-3)
m= y2-y1/x2-x1
-3-0/9-0= -3/9=-1/3
slope= -1/3
Since we already have the point (9,-3),
enter the information above into the point slope form formula.
y-(-3)=-1/3(x-9)
<u>y+3=-1/3(x-9)</u>
6.
3h--> $75
1h--> $15
a)
Standard form: Ax + By = C
m(slope)=15
y=15x
y-15x=0
-15x+y=0
<u>15x-y=0</u>
b)
<u>10 hours of work---> $150</u>
Answer:
Step-by-step explanation:
When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign of each term. That means, the expression remains the same. Just remove the parentheses

Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most that is the area of the rectangle cannot be greater than 400
Substitute the given value into the inequality expression
Lh ≤ 400
Given
L = 16
16h ≤ 400
Divide both sides by 16
16h/16 ≤ 400/16
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension
2x + 5 = 27
2x + 5 (-5) = 27 (-5)
2x = 22
2x/2 = 22/2
x = 11
hope this helps
